Study of Nivolumab, Cabiralizumab, and Stereotactic Body Radiotherapy (SBRT) for Locally Advanced Unresectable Pancreatic Cancer

This is an interventional treatment trial for Pancreatic Cancer Read More

Inclusion Criteria:

• Histologically confirmed locally advanced, unresectable pancreatic cancer as defined by NCCN Guidelines 3.2017
• Locally advanced unresectable disease is defined by the NCCN as:
• Tumors of the head that have greater than 180 degrees of SMA encasement or any celiac abutment, unreconstructable SMV or portal occlusion, or aortic invasion or encasement.
• Tumors of the body with SMA or celiac encasement of greater than 180 degrees, unreconstructable SMV or portal occlusion, or aortic invasion.
• Tumors of the tail with SMA or celiac encasement of greater than 180 degrees. Irrespective of location, all tumors with evidence of nodal metastasis outside of the resection field are deemed unresectable.
• Patients must agree to pretreatment and on treatment tumor biopsy
• ECOG performance status of 0 or 1
• Completion of at least 2 months, but no more than 6 months of standard induction chemotherapy for LAPC, which must include either FOLFIRINOX or gemcitabine and nab- paclitaxel, preferably within 2-4 weeks but no longer than 8 weeks.
• Normal organ and marrow function as defined below:
• absolute neutrophil count ≥ 1,500/mm3
• platelets ≥ 100,000/mm3
• total bilirubin ≤ 1.5 x institutional upper limit of normal (except participants with Gilbert's syndrome who must have normal direct bilirubin)
• AST(SGOT) and ALT(SGPT) ≤ 2 × institutional upper limit of normal
• creatinine ≤ 1.5 mg/ dL OR
• creatinine clearance≥ 30 mL/min (as estimated by Cockcroft Gault Equation)
• Ability to understand and sign a written informed consent document. Participant must have willingness and ability to comply with scheduled visits, treatment plans, laboratory tests and other study procedures.
• Women of childbrearing potential (WOCBP) must have a negative serum or urine pregnancy test (minimum sensitivity 25 IU/L or equivalent units of HCG) within 24 hours prior to the start of study treatment.
• WOCBP must agree to follow instructions for method(s) of contraception for the duration of treatment with study treatment(s) and for a total of 5 months post-treatment completion.
• Males who are sexually active with WOCBP must agree to follow instructions for method(s) of contraception (see appendix 1) for the duration of treatment with study treatment(s) and for a total of 7 months posttreatment completion. In addition, male participants must be willing to refrain from sperm donation during this time.

Exclusion Criteria:

• Resectable, borderline resectable or metastatic disease
• Interstitial lung disease that is symptomatic or may interfere with the detection or management of suspected treatment-related pulmonary toxicity.
• Participants with a condition requiring systemic treatment with either corticosteroids (> 10 mg daily prednisone equivalents) or other immunosuppressive medications within 14 days of study treatment administration except for adrenal replacement steroid doses > 10 mg daily prednisone equivalent in the absence of active autoimmune disease.

Note: Treatment with a short course of steroids (< 5 days) up to 7 days prior to initiating study treatment is permitted.

• Current or history of clinically significant muscle disorders (eg, myositis), recent unresolved muscle injury, or any condition known to elevate serum CK levels
• Uncontrolled or significant cardiovascular disease including, but not limited to, any of the following:
• Myocardial infarction or stroke/transient ischemic attack within the past 6 months
• Uncontrolled angina within the past 3 months
• Any history of clinically significant arrhythmias (such as ventricular tachycardia, ventricular fibrillation, or torsades de pointes)
• History of other clinically significant heart disease (eg, cardiomyopathy, congestive heart failure with New York Heart Association functional classification III to IV, pericarditis, significant pericardial effusion, or myocarditis)
• Cardiovascular disease-related requirement for daily supplemental oxygen therapy.
• Evidence of uncontrolled, active infection, requiring parenteral anti-bacterial, anti-viral or anti-fungal therapy ≤ 7 days prior to administration of study medication.
• Any uncontrolled inflammatory GI disease including Crohn's Disease and ulcerative colitis.
• Participants with active, known, or suspected autoimmune disease. Participants with vitiligo, type I diabetes mellitus, residual hypothyroidism due to autoimmune condition only requiring hormone replacement, euthyroid participants with a history of Grave's disease (participants with suspected autoimmune thyroid disorders must be negative for thyroglobulin and thyroid peroxidase antibodies and thyroid stimulating immunoglobulin prior to first dose of study treatment), psoriasis not requiring systemic treatment, or conditions not expected to recur in the absence of an external trigger are permitted to enroll after discussing with the Principal Investigator.
• Concomitant use of statins while on study. However, a patient using statins for over 3 months prior to study drug administration and in stable status without CK rise may be permitted to enroll.
• Non-oncology vaccine therapies for prevention of infectious diseases (eg, human papillomay virus vaccine) within 4 weeks of study drug administration. The inactivated seasonal influenza vaccine can be given to patients before treatment and while on therapy without restriction. Influenza vaccines containing live virus or other clinically indicated vaccinations for infectious diseases (ie, pneumovax, varicella, etc) may be permitted, but must be discussed with the principal investigator and may require a study drug washout period prior to and after administration of vaccine.
• Known human immunodeficiency virus (HIV), known active hepatitis A, or known hepatitis B or C infection.
• History of acute diverticulitis within the last 6 months, or current chronic diarrhea
• Pregnant or lactating women.
• Women of childbearing potential (WOCBP) with either a positive or no pregnancy test (serum or urine) at baseline. (Postmenopausal women must have been amenorrheic for at least 12 months to be considered of non-childbearing potential.)
• WOCBP who are unwilling or unable to use an acceptable method to minimize the risk of pregnancy (see appendix 1) for the entire study period and for at least 5 months after the last dose of investigational product. WOCBP who are continuously not heterosexually active are also exempt from contraceptive requirements, but still must undergo pregnancy testing as described in section - Sexually active fertile men not using effective birth control if their partners are WOCBP
• History of primary immunodeficiency.
• History of organ allograft or allogeneic bone marrow transplant.
